COMBINED CONCENTRA'TING AND AMALGAMATING TABLE.

SPECIFICATION forming part of Letters Patent No. 760,213, dated May 1'7, 1904.

Application filer. December 3, 1902. Serial No. 183,781. (No model.)

To all whom it pray concern:

Be it known that I, J GEN KLEIN, of the city of Desloge, St. Francois county, State of Missouri, have invented certain new and useful Improvements in a Combined Concentrating and Amalgamating Table, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to a combined concen trating and amalgamating table; and it consists of the novel construction, combination, and arrangement of parts hereinafter shown, described, and claimed.

In the drawings, Figure 1 is a top plan view of my invention. Fig. 2 is a side elevation of my invention ready for use, parts being broken away. Fig. 3"is a longitudinal midsection of the same, the wire-gauze above the flooring of the concentratingtable being omitted. Fig. 4 is a transverse section taken on the line w of Fig. 1. Fig. 5 is a detail View in section, parts being broken away, showing the means by which my invention is supported when in use. Fig. 6 is a detail cross-section showing the opening in which one of the suspending-rods operates.

My invention is what might be termed a concentrating-table and an amalgamatingtable; but in reality when my invention is equipped for amalgamating purposes the same table may be used for concentrating purposes;

but when I desire to construct my table for concentrating lead ores or any class of ores that contain no free gold I omit certain features of construction,which will be more fully hereinafter described.

' Referring to the drawings, 1 indicates transverse timbers, and 2 the legs supporting the same, and 3 longitudinal timbers, the said transverse timbers, the longitudinal timbers, and the legs forming the supporting-framework for my table. In this connection I desire to state that any other suitable construction of framework may be employed for supporting the table, as I do not claim in this invention any specific construction by which my table may be supported when in operation.

I will now proceed to describe the construc- 5 0 tion of the table in detail. The framework of the table is composed of longitudinal side timbers 4, transverse end timbers 5, a longitudinal center timber 6, and transverse center timbers 7, all of which being suitably fastened together so as to form the framework of the table. The framework of the table also has secured to it an upright side piece 8 at the front or top of the table, which is secured in any suitable and mechanical manner. In this connection I desire to state that the framework of my table may be constructed in various ways so as to provide a rigid and solid framework of sufiicient strength to stand the jarring, moving, or shaking motion to 5 which the table is subjected while in operation. On top of the framework, as hereinbefore described, a wooden flooring 9 is made, which is secured to the framework in any suitable and mechanical manner. 'On top of 7 the wooded flooring 9 I cover my table with linoleum or sheet-rubber, and on top of the linoleum or sheet-rubber I place a layer of amalgamated wire-gauze 10, the wire out of which the gauze is made containing about sixty per cent. of copper alloy, and on top of the amalgamated wire-gauze I place a series of copper channels 11. It will be noticed in this connection that I do not graduate my channels; but they all terminate on 30 the same transverse line of the table, (see Fig. 1 for illustration,) thus leaving at the lower end of the table a smooth and unbroken surface a, which is rectangular in dimensions. In addition to the series of copper channels 5 11 I also employ a series of check-blocks 12. These check-blocks are shown as triangular, their apexes extending toward the front or top of the table; but I desire to state in this connection that I can use any shape or dimen- 9 sion of block or any other suitable means to direct, divert, and distribute the pulp. These blocks are preferably made of wood, and it will be noticed in this connection that I use where the slush enters the table a greater number of these blocks than at the point where the clear water passes, because I desire to direct, divert, and distribute the slush and pulp through the blocks, thus completely distributing the feed and concentrating the pulp.

I do not wish to be limited to the precise arrangement, location, and number of blocks 12 illustrated in the drawings, as a greater or less number thereof may be employed, and they may be disposed over a greater or less surface of the concentrating-table and relative to the surface occupied by the channels 11-, the arrangement shown in the drawings being merely illustrative of one arrangement which I find satisfactory.

The location of the blocks over the surface of the table will completely and effectively distribute, in connection with a jarring, moving, or shaking surface, the substances moving over the surface of the table while in operation at each point where ablock is located, by which a greater degree of concentration may be obtained than is now obtained by using continuous or unbroken channels or riffles. These check-blocks 12 are located on top of the amalgamated wire-gauze 10 and are secured to the table by any suitable means. I have found by practical experiments that by using these check-blocks in conjunction with the copper channels or rifl'les more effective concentration may be obtained than by using continuous or unbroken channels or riffies alone.

I prefer that the channels 11 should be arranged in a direction approximately parallel with the lines of movement of the table and alsothat the portions of the flooring 9 upon which both the channels and the distributing check-blocks are arranged should be on a common plane.

l3,indicates the slush or pulp box, which is mounted over the front or top edge of the table, as illustrated in Figs. 1, 2, and 4:, the same being provided with a slush or pulp compartment 14 and a clear-water compartment 15. This box is independent of the concen trating-table, and the operation of the concentrating-table does not in any manner act on the box. Secured to the longitudinal center timber 6 of the framework'of the concen trating-table is an H-shaped iron, and secured to the longitudinal center piece of the framework on which the concentrating-table is lo-' cated are right-angular guide-pieces 17. It will be noticed by referring to Fig. 4, wherein this construction is shown, that the H-shaped cated on each side of the framework and suitably secured thereto are three suspensionstandards 18, (three being on each side of the framework,) the base of said suspension-standards being suitably secured to the framework of the superstructure. Pivotally secured to the framework of the concentrating-table are rods 19, the ends of which are screw-threaded to receive turnbuckles 20. The ends 21 of the suspension-standards 18 are provided with enlarged openings 22, in which are mounted rods 23, the lower ends of which are screwthreaded to receive the turnbuckles 20. The upper ends of said rods are provided with holes 24 to receive pins 25, by means of which said rods and the parts attached to the lower ends are suspended from the ends 21 of the suspension-standards 18. The enlarged openings 22 are for the purpose of permitting the .rods 23 to have a swinging motion, as it is of the suspension-standards 18 are secured together by means of transverse rods 26. It will be seen from the foregoing description that my concentrating-table is suspended and may be adjusted at any degree of inclination, that it may be transversely inclined at various angles and longitudinally inclined at various angles, that it is also held from lateral movement, and that by the same being suspended it is easily operated, as the only force necessary to operate the table is to give it a swinging or jarring motion.

When my concentrating-table is constructed as hereinbefore described and mounted as described, I preferably operate it by means of my compressed-air motor patented to me on November 5, 1901, No. 686,087; but I may employ other means for operating the table. I have found from experience that to effect the proper concentration and amalgamation I need a jarring or shaking motion, as a jarring motion facilitates amalgamation and also concentration.

The suspension-standards 18 are laterally braced by means of rods 27.

It will be seen from the foregoing description that the top of my table is provided with a smooth and unbroken surface a, so that the water on emerging from the water-box has a clean sweep over said portion of the table in order that any foreign substances of no value may be washed off the table as quickly as possible. The check-blocks 12 I claim as a great benefit to check the current on any jarring, moving, or shaking concentrating-table and, furthermore, as an effective means to direct, divert, and distribute the slush and pulp through the blocks over the table, thus distributing the feed and concentrating the pulp.

When I desire to use my table as an amalgamating table, I amalgamate the copper channels 11 and the wire-gauze 10. This is done in cases where the ores to be treated contain free gold. When I use my table for concentrating lead ores or any class of ores that contain no free gold, I omit, or it is not necessary, rather, to use the amalgamated wiregauze or to amalgamate the copper channels. However, when my table is equipped as an of inclination, and means for imparting motion to said table, substantially as specified.

2. The combination of a movable table, aseries of ungraduated channels secured to a portion of the upper surface of the table, a feedtrough arranged substantially parallel with the said channels through which the pulp and water are distributed to the table, and checkblocks carried by the upper surface of the table and arranged between the feed-trough and the channels, the number of check-blocks being greatest opposite the portion of the trough through which the pulp is fed and less opposite the portion through which the water is fed, substantially as set forth.

3. A combined concentrating and amalgamating table having its top surface provided with amalgamated wire-gauze, and a portion of its wire-gauze surface provided with a series of ungraduated amalgamated copper channels, a series of check-blocks and an unbroken, smooth, defined surface at its lower end; means for suspending said table, and means for imparting motion to said table, substantially as specified.

In testimony whereof I aflix my signature in presence of two witnesses.

JOHN KLEIN.
